Comments
This enzyme is composed of the N-terminal 5'-3' exonuclease (E.C. 3.1.11.3) domains, 3'-5' exonuclease (E.C. 3.1.11.1) domain, and the C-terminal polymerase (E.C. 2.7.7.7) domains. However, the active site of the 3'-5' exonucleae is obsolete, unlike its conterpart from E. coli (M00055 in EzCatDB). The DNA polymerase belongs to the type-A family.
The mechanism of 5'-3' exonuclease has not been elucidated yet.
According to the literature [6] & [12], the mechanisms of this enzyme is as follows:
(A) Transfer of phosphoryl group from NTP to DNA.
(A1) Divalent metal-1, which is bound to Asp785 and Glu786, interacts with acceptor, 3'-OH of DNA and activates it by lowering its pKa.
(A2) The acceptor, 3'-hydroxyl group, makes a nucleophilic attack on the transferred alpha-phosphoryl group.
(A3) Divalent metal-1 and metal-2 stabilize the transition state by interacting with the transferred group, whereas the leaving groups, beta- and gamma-phosphate groups, are stabilized by divalent metal-2 along with mainchain amide of Gln613 and Ile 614, sidechain of Arg682, His639, Arg659 and Lys663.
